OnItemSelectedListener useless, have BUG, ​​every time the switching time Item, Item background will flash, and when the focus disappeared Activity will go first to add a control that has the focus coming in, that whenever the switch once Item, Focus disappear -> Focus jump outside the ListView control -> Focus and then jump back to the next Item.
But the problem has been resolved, I TableLayout instead of using ListView implementation, there will not be above BUG

Focus listview's a good solution, you have to first get your child focus, acquisition method android: descendantFocusability = "beforeDescendants", so that you can get every child to focus, listview achieve setOnItemSelectedListener then implement the following code in the callback in can,
public void onItemSelected (AdapterView parent, View view, int position, long id) {
mListView.clearFocus ();
ViewGroup viewGroup = (ViewGroup) view;
viewGroup.setDescendantFocusability (ViewGroup.FOCUS_BEFORE_DESCENDANTS);
viewGroup.requestFocus ();
}
Perhaps a better achieved.
